- Process Description
The data was downloaded from the USGS Data Depot as a nationwide dataset. The shapefile was not defined, so as it was determined
in overlaying to other defined shapefiles, it was determined that while the website indicated the following:
projection Lambert Azimuthal Projection
units meters
major axis 6370997.00000
minor axis 0.00000
radius of the sphere of reference 6370997.00000
longitude of center of projection -100 0 0.00000
latitude of center of projection 45 0 0.00000
false easting 0.00000
false northing 0.00000
It really was in Geographic, NAD83. It was defined and metadata created.
Then the quads covering the state of Arizona were extracted and saved as a new shapefile for ease of use.
